The Configuration register is 8 bits, read/write, and
contains the SMBus timeout disable bit, fault queue
enable bit, the temperature alarm output polarity select
bits, the interrupt mode select bit, and the shutdown
bit. Registers THIGH and TLOW are 16 bits, read/write,
and contain the values that trigger ALERT. Register
THYST is 16 bits, read/write, and contains the values by
which the temperature must rise or fall beyond THIGH or
TLOW, before ALERT deasserts.
Control Registers (MAX6635)
Seven registers control the operation of the MAX6635
(Figure 7 and Tables 2 through 7). The Pointer register
is the first addressed and determines which of the other
six registers is acted upon. The other six are the
Temperature, Configuration, High-Temperature
(THIGH), Low-Temperature (TLOW), Maximum
Temperature (TMAX), and Hysteresis (THYST) registers.
The temperature value is stored as 12 bits plus a sign
bit, read only, and contains the latest temperature data.
The true register length is 16 bits, with the lower three
used as status bits. The digital temperature data con-
tained in the temperature register is in °C, using a
two’s-complement format with 1LSB corresponding to
0.0625°C.
The Configuration register is 8 bits, read/write, and
contains the SMBus timeout disable bit, fault queue
enable bit, the temperature alarm output polarity select
bits, the interrupt mode select bit, and the shutdown
